Specicationof Letters Patent No.

To all whom t may concern: f Be it known that I, ALONZO HITCHCOCK, ofthe city of Chicago and State Of Illinois, have invented a new andimproved mode yof constructing doors for dwellings to prevent the waterfrom running under the bottom of outside doors in exposed situations,also for keeping out the cold winds; and I Ido hereby declare that the`following is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part Of the specifications, in which- Figure 1, is a front viewof the lock rail, orv edge of the door, when closed, showing the Vshaped groove cut in the bottom of the door, by which a sharp edgeorangle is formed at s, which causes the water when running down on theoutside lof the door to break olf suddenly and run down the inclinationof the carpet strip or door sill, outside of the building. To make itstill more secure against rain and wind, I attach at the top or angle ofthe grove a, a hinged weatherstrip, hung by staple and links, so that itmay be raised and lowered when the door is opened and closed, by reasonof the elevated surface or plane E, Figs. r2, and 3. Fig. 3 is theground plan or bottom of the elevated surface. Fig. 4 shows theelevation of the same, the perpendicular being from 4f, to 3,

fourths of an inch; from l to 3, One inch.' Fig. 2, shows the back edgeof the door together with the elevated surface and the weatherstrip,when the door is closed.. The instant the door is opened the weatherstrip must rise, as it bears upon the top of the elevated surface orplane, E, the end of the weatherstrip following as near as maybe in thelines y y y g/ y, in all the figures, Fig. 5, gives nearly a correctform of a transverse 12,388, dated February 1s, 1855.

section if it were cut off at the dotted lines g, g, Fig. 3. Fig. 6,shows a section of the weatherstrip and the manner of fastening 4at thetop. I also bevel the carpet strip 0 from the center of the door out, soas tO form an inclined plane to facilitate the water running Off.

F, Fig. l, isa section of the lioor.

These drawings and figures are calculated lfor doors one and a halfinches thick, the

-precise form of this elevated surface is difficult `to represent indrawings, but with those figures, any practical mechanic can not fail tomake it. The exact proportions must varyr a little for differentthicknesses of doors.

e, Fig. l,shOws a piece of listing of cloth fastened on the inside ofthe groove to shut down tight On the carpet strip C, vwhich also servesto keep out the cold air.

To make it still more plain in the construction, I will refer again toFig. 8, which is full size. All that part Of the elevated surface, fromH, to K, is no more than one fourth Of an inch thick, 8 8, showing thescrew holes through which the screws are driven to hold down to itsproper place.

I do not claim the V shaped groove, nory ALONZO HITCHCOCK.
